RESUMO
BACKGROUND A dramatic rise in the rate of clostridium difficile infection (CDI) in patients with inflammatory bowel disease (IBD) has been reported in recent years. METHODS In this observational case control study, 65 patients were included and were divided into two groups of IBD + CDI as case group and IBD without CDI as control group. RESULTS 35 patients who had positive test for clostridium difficile were assigned to the case group. The control group consisted of 30 patients with negative test for clostridium difficile. Pancolitis was seen in the cases more statistically significant than the controls and proctitis was seen more among the controls than the cases (p = 0.001). The cases were on immunosuppressive (p = 0.001) and antibiotic (p = 0.02) therapy more than the controls. Colonoscopic findings revealed more severe and extensive inflammation among the cases versus milder inflammation among the controls, but these differences were not statistically significant (p = 0.2). Colectomy was seen in 10% of controls and none of the cases and this difference was statistically significant (p value = 0.05). More fecal calprotectin were seen among the cases than the controls and this difference was statistically significant (p < 0.05) CONCLUSION This study showed more clostridium difficile infection among the patients on antibiotic or immunosuppressive therapy. Pathological investigation revealed more severe and extensive inflammation among the cases than the controls. Cases had clinically more severe signs and symptoms with higher mayo scores than the controls. ESR (Erythrocyte sedimentation rate) and fecal calprotectin were higher in patients with positive clostridium difficile infection and serum albumin was lower in such patients.
RESUMO
AIM: Adequacy of enteral nutrition (EN) alone as stress ulcer prophylaxis (SUP) is controversial. The aim of this study was to compare efficacy of EN alone and ranitidine plus EN as SUP. METHOD: Critically ill adults with indications to receive SUP were randomized to ranitidine 50 mg IV every 8 h plus EN (SUP) or EN alone (non-SUP) group for 7 days. Besides, endoscopy was performed at the time of recruitment and on day 7. RESULTS: During the study period, only one patient in each group of SUP and non-SUP experienced gastrointestinal bleeding. At the time of recruitment, gastric erosion and erythema were the most endoscopic findings in the SUP and non-SUP groups. These findings did not significantly change at the end of the study (p = 0.21). CONCLUSION: EN was at least effective as ranitidine plus EN as SUP.

BACKGROUND/AIMS: Gastrointestinal disorders are important side effects of aspirin therapy, even if the low-dose enteric-coated form is administered. The aim of the current study was to present the upper and lower endoscopic features of patients with gastrointestinal hemorrhage using low-dose enteric-coated aspirin. MATERIALS AND METHODS: This prospective study was conducted among 633 consecutive patients with gastrointestinal hemorrhage who admitted to our tertiary referral hospital for endoscopy assessment. Patients were divided into two groups as low-dose aspirin users (n=168) and non-aspirin users (n=495). Aspirin users included those who were taking 80-100 mg of enteric-coated aspirin per day. RESULTS: Ulcer lesions were found in 78 patients in the aspirin user group and in 113 patients in the control group. Prevalence of duodenal ulcer was statistically similar between the two groups; however, gastric ulcer was seen more in the aspirin-user group. The use of low-dose aspirin could strongly predict gastric ulcers in the patients examined by endoscopy (p<0.001). Overall prevalence of peptic ulcer disease in those with confirmed Helicobacter pylori infection was significantly higher than in non-infected ones (p<0.001). The presence of this infection was strongly associated with peptic ulcer disease in the aspirin-user group (p<0.001). Multivariable analysis also demonstrated that the use of aspirin had a main triggering effect on short-term mortality following gastrointestinal endoscopy (p=0.003). CONCLUSIONS: Low-dose enteric-coated aspirin causes significant gastric endoscopic lesions and even predicts mortality due to progression of gastrointestinal disorders.

Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) has evolved as the surgical procedure of choice for ulcerative colitis (UC). The aim of our study was to evaluate the quality of life (QOL) of UC patients who underwent this procedure over 5 years ago. Thirty-nine UC patients who underwent restorative proctocolectomy with IPAA were interviewed by the validated inflammatory bowel disease questionnaire (IBDQ). Each patient was assigned a score, ranging from 32 to 224, in which the highest score indicates the best QOL. QOL for postoperative patients was good in 15 (38.5 %), regular in 23 (59 %), and bad in 1 (2.6 %) patient. QOL was not significantly influenced by age or gender of the patient. The emotional aspect received the highest score in the IBDQ and for each question that was analyzed separately; most of the patients were pleased and thankful with their lives and this question received the highest score. Long-term QOL was good in UC patients who underwent IPAA. This operation should be considered as the first choice since the patients were stable after long-term follow up.

Cholangitis is relatively uncommon but associated mortality is high due to the predisposition in people with underlying disease. For this recognition of contributing risk factors is necessary. Therefore, the present descriptive- analytical cross-sectional survey was designed to determine contributing risk factors for post-ERCP cholangitis in patients with pancreatic cancer. From 2005 to 2010, 110 consecutive cases of pancreatic cancer attending to a tertiary referral centre (Taleghani Hospital), Tehran, Iran were recruited. The patients all underwent stenting via endoscopic retrograde cholangiopancreatography (ERCP). On univariate analysis, a metallic stent type (95% confidence interval (CI) 1.025-11.34, P=0.037), having no jaundice (1.44-2.22, P=0.009), having no pain (1.32-1.91, P=0.026), a history of prior ERCP (1.16-10.37, P=0.020), and having a proximal biliary stone (1.002- 5.93, P=0.046) were related to cholangitis. However on multivariate analysis, none of these factors were found to be contributing risk factors. Cholangitis is avoidable with adequate biliary drainage. Because success rates are higher and complication rates lower for endoscopists performing large volumes of ERCP, performance of the procedure should be concentrated as much as possible in institutions with endoscopists having adequate experience. Patients with a high risk for complications may be best served by referral to an advanced center.

PURPOSE: Lateral internal sphincterotomy has been the gold standard treatment for chronic anal fissure, but it still carries the risk of permanent damage of the anal sphincter, which has led to the implementation of alternative treatment like botulinum toxin injection. The aim of this randomized prospective controlled trial was to compare the efficacy and morbidity of botulinum toxin injection and lateral internal sphincterotomy in the treatment of chronic anal fissure. METHODS: Fifty consecutive adults with chronic anal fissure were randomly treated with either lateral internal sphincterotomy or botulinum toxin (BT) injection with 50 U BT into the internal sphincter. The complications, healing and recurrence rate, and incontinence score were assessed 2, 3, 6, 12 months after the procedure. RESULTS: Inspection at the 2-month visit revealed complete healing of the fissure in 11 (44 %) of the patients in the BT group and 22 (88 %) of the patients in the lateral internal sphincterotomy (LIS) group (p = 0.001). At the 3-month visit, there was no significant difference between the two groups in healing. The overall recurrence rate after 6 months in the BT group was higher than in the LIS group (p < 0.05). In the 3-month follow-up, the LIS group had a higher rate of anal incontinence compared to the BT group (p < 0.05). The final percentage of incontinence was 4 % in the LIS group (p > 0.05). CONCLUSIONS: The treatment of chronic anal fissure must be individualized depending on the different clinical profiles of patients. Botulinum toxin injection has a higher recurrence rate than LIS, and LIS provides rapid and permanent recovery. However, LIS carries a higher risk of anal incontinence in patients.

Methemoglobinemia and hemolysis are rare findings following phosphine poisoning. In this paper, a case of aluminum phosphide (AlP) poisoning complicated by methemoglobinemia and hemolysis with a successful treatment is reported. A 28-year-old male patient presented following intentional ingestion of an AlP tablet. In this case, hematuria, hemolysis and methemoglobinemia were significant events. A methemoglobin level of 46% was detected by CO-oximetry. The patient was treated with ascorbic acid and methylene blue and he also received supportive care. Two weeks after admission, the patient was discharged from the hospital. Hemolysis and methemoglobinemia may complicate the course of phosphine poisoning.
RESUMO
BACKGROUND: Confirmation of cholangiocarcinoma and other malignant bile duct stenosis is challenging. The aim of the current study was to assess the accuracy of brush cytology for diagnosis of malignant biliary strictures. METHODS: 105 patients with hepatic biliary strictures undergoing ERCP were included in this study. Prospectively collected data included symptoms, results of biochemical testing and imaging procedures, as well as details of ERCP. Exclusion criteria were: 1) strictures that would not permit passage of guidewire and brush accession; and 2) post-operative strictures. Brushings of the bile duct strictures were performed. All patients were followed for at least 6 months. The final diagnosis was confirmed following surgery, histopathological diagnosis of the lesion, radiological infiltration of adjacent organs or metastases, or after at least a 6-month follow-up. RESULTS: 88 brush samples from 88 patients were of appropriate quality. The overall diagnostic sensitivity and specificity for malignant nature of biliary strictures were 40.7% and 100%, respectively. The sensitivity was 66.6 % for ampullary carcinomas, 36.3% for pancreatic cancer and 32.5% for cholangiocarcinomas. CONCLUSIONS: Despite the low sensitivity, due to the relative ease and safety, brush cytology should remain the first choice for diagnosis of causes of biliary strictures.
